"But they could stop there and everybody in NATO would shrug their shoulders and they would keep Crimea. Why insist on further escalation?" They say, they stopped there - and that they will not tolerate a military occupation of the autonomous eastern ukraine provinces. Not that they want to occupy whole ukraine. So I do not see them insist on further escalation. But the west has said - it will not accept the crimea annexion. So this conflict will remain unsolved, if no side will move.
